Donald Trump has a million reasons to allow himself — and his complicated hair — to be mocked on the “Comedy Central Roast of Donald Trump,” to be taped March 9 in New York. The real estate mogul and TV star is getting a seven-figure payment for his participation, say sources. Anyone who attended the Friars Roast of the billionaire a few years ago — where Trump was ridiculed mercilessly — might wonder why he’d put himself through it again. But The Donald is no masochist. Eagle-eyed readers of the press release noticed, “Andy Litinsky from Trump Productions LLC is a producer on the project.” Hmmm — if Trump is co-producing, shouldn’t he be getting paid? A source confirmed to Page Six, “Donald is being paid a fortune — over $1 million.” A rep for Trump said, “I can’t comment on terms, but it is a very lucrative deal for Donald and will be a great show with lots of big names on the dais.”
